Description
The present invention relates to the described sheet feeder of claim 1 preamble.
A modal defective is in the operation of sheet feeder: two overlapping paper are attached together each other to be taken off simultaneously from the paper pile and transport.In the sort of existing sheet feeder described in claim 1 preamble, (see US-A-3885784 and DE-A, 201069) imagination has the rocking arm of inhaling the hole by one and solves above-mentioned defective, like this, in operation earlier with this be contained in the parallel plane oscillating axle of paper on rocking arm be pressed on the paper pile, then after suction hole and suction source are connected, with certain speed it is put from the paper pile, a piece of paper that imagination just will directly be inhaled is taken away, following a piece of paper is then because effect of inertia, although between two pieces of paper, exist certain adsorption affinity, can under this quick action, it not taken away yet.In this case, the paper pile is placed vertically, and its lower edge is rested in deposit the storehouse and deposit on the bottom of the reservior to the front upper place bevelled, and the paper pile is pressed against it forward on the described rocking arm by a top board that is supported on its back, and rocking arm is " F " shape.Two parallel leg of " F " shape rocking arm have inhales the hole and constitutes actual separating member, when paper being inhaled from residue paper pile paper be attracted on the rocking arm and be positioned at can by one continuously the annular sheet-transport belt of operation with its plane of taking away.This sheet-transport belt is one by same distance the endless chain of inhaling the paper member to be housed, and rocking arm is connected with a distributing valve by flexible pipe with the suction hole that sheet-transport belt is inhaled the paper member, and this distributing valve and sheet-transport belt rotate synchronously, and in time open and close the suction pipeline.Rocking arm is by cam drive; rocking arm is inhaled the hole and connected with the suction source when rocking arm is in the rear position of pressing the paper pile; cut off the suction pipeline and arrive at rocking arm when paper inhaled anterior position from the paper pile, on this anterior position paper by through here and in time and the suction paper member of suction source connection it is held and transports.
Owing to adopted the rocking arm of this quick swing and its anterior position was transferred to this rocking arm in requirement from its rear position in 0.01 second driving device, also because the suction paper member that acts on rocking arm and the conveyer chain requires co-operative control accurately, this existing sheet feeder just has quite complicated structure.In addition, operation just depends on effect of inertia because the paper pile is said good-bye, a piece of paper is separated adopted high-speed and act on second force of inertia on the paper and whether be enough to overcome adsorption affinity between the two pieces of paper, and this also depends on the adsorption strength between the two pieces of paper.And, owing in depositing the storehouse, require the top board that continues the power of doing to be set in paper pile back, like this, the depositing the storehouse and just can not deposit the storehouse as a centre of this sheet feeder just can not be as a storehouse of depositing that is arranged between two paper processing apparatus that do not possess synchronous working cycle or identical process velocity.Usually, the storehouse is deposited in centre must successively deposit paper from first processing unit (plant) off and on, must it be sent to second processing unit (plant) one by one by the cycle of operations that is equivalent to second processing unit (plant) again simultaneously.
The objective of the invention is to simplify and the sheet feeder that improves at the sort of relevant paper pile separating device described in claim 1 preamble, make the operation of saying good-bye have very high reliability, in addition, in the total design, make this sheet feeder deposit the storehouse as a centre.
This purpose is finished by characteristics described in claim 1 characteristic of the present invention.
Have the separating member of inhaling face according to claim 1 and itself in the counting machine of similar bill in batch, particularly bank note, generally acknowledge it is prior art (seeing EP-A-0311567 the applicant's patent).But, these separating members are to make that part that abuts on the bank note on the separating member suction face to be inserted into the back side of a next separating member on design and structure, and a collection of bank note through counting is all moved on on the slip surface of this separating member another side continuously.In addition, bank note is vertically to be placed on the depositing in the storehouse of level in batch, and withstands on the back of bank note in batch with a top board.Therefore, this paper-money counting machine does not relate to the present invention as the middle sheet feeder in storehouse of depositing.
The principal advantages of sheet feeder of the present invention is: because its suction mask has special radian on the separating member of slippage, paper pile on the narrow limit of the paper nethermost paper of pile just is not bent away from simply, but also stand a kind of torsional deflection, after this, by holding it under the state that separates with the paper pile with separation pig in the back.In addition, also can earlier narrow limit further be bent away from the paper pile by separation pig.Here, the narrow limit of next paper might be adsorbed on the nethermost paper, but be that the narrow limit that can be bent away from takes up to a certain extent in fact at the beginning, but can not twist thereupon, or rather, because its inherent elasticity or bending stiffness, before maximum deflection was made on nethermost narrow limit, this narrow limit that is taken up can be left nethermost narrow limit voluntarily and spring back to its original state.Therefore, be to have used paper elastic to torsional deflection in the operation of saying good-bye.By selecting one at least 10 ° for use, be preferably 15 °-25 ° so enough big suction face trailing edge leaning angles, in fact the fault rate of the operation of saying good-bye can drop to zero.After separating member passed through, separation pig just made narrow limit remain on it and is bent away from state, thereby can make the chuck of a belt conveyor directly it be clamped and transport, but also can with adjustable suction nozzle it further be thrown off from remaining paper pile earlier, by belt conveyor it was transported again.
Because paper is to pack into from above to deposit the storehouse and from depositing below it being taken away of storehouse, sheet feeder of the present invention is deposited the storehouse in the middle of can be used as fully, and for example the paper cutting after a paper counting machine and will count becomes to be used as the centre between the guillotine of individual bank note and to deposit the storehouse.This device in order to processing bank note does to have explanation in the applicant's EP-B-167196.

Figure 19 is another embodiment of sheet feeder and the cooresponding section-drawing of Fig. 7, and this feeder has towards different separating members and separation pig, different chain guiding, and can directly the paper of telling be sent on the chain chuck;
Figure 19 a, 19b and 19c be embodiment illustrated in fig. 19 in the paper pile is said good-bye process successively with 7a, 7b and the cooresponding continuous handling state of 7c.
As shown in Figure 1, sheet feeder B deposits the storehouse as a centre, is arranged between two processing stand A and the C, and this two processing stand is operated with different work speeds or different cycle of operationss.Related in this example is the processing of paper printing spare.For example, at processing stand A is a serial-number printing machine, bank note on every folder is numbered printing successively, in sheet feeder B, paper is deposited in the middle of doing, paper is packed the depositing the storehouse of sheet feeder into from above and is taken away from below, at processing stand C, processing of cutting point for example, here only make simple diagram, folder is cut into individual bank note, and a kind of device that has the processing bank note folder of serial-number printing machine and follow-up processing of cutting point does to have explanation in the applicant's EP-B-167196.
As Figure 1-3, processing stand A and sheet feeder B are contained on the same frame 21, and are connected with each other by a chain grasping system, generally are provided with a chain 22, sprocket wheel 23 and chuck 22a.As Figure 1-3, sprocket wheel 23 is positioned at an end of clamping chain.Paper W through seal number is sent to sheet feeder B from station A along direction shown in the arrow F1 one by one by the chain grasping system, and paper enters the unlimited storehouse 24 of depositing from top along direction shown in the arrow F2, forms paper pile S.Roller 25 has to be made paper be convenient to pack into to deposit the effect in storehouse 24.Deposit storehouse 24 and have a bottom 26, a rear wall 27, two sidewall 28(Fig. 2 and 3) and an antetheca, bottom 26 is fixed on supports 21a(Fig. 7) on, only the paper pile being made part supports and makes by coming the paper direction freely to hang at the narrow limit R of its fwd, antetheca is made of guide rail 29, and this will be illustrated below.Along narrow limit, just perpendicular to the direction of Fig. 1 drawing, be provided with the endless chain 18 that can divide a word with a hyphen at the end of a line, its route of dividing a word with a hyphen at the end of a line is an oblong as shown in Figure 4 basically.Plurality of separate member 1 and separation pig 11 are housed on chain 18, and these will be illustrated below, and its acclivitous upper surface is in order to the narrow limit R of supporting paper pile S, thereby make the corresponding K/UP obliquely of narrow limit R.For chain 18 is led, be provided with two sprocket wheels 19, one of them is by a motor 20(Fig. 1) transmission, also be provided with two side guide 38(Fig. 4), a lower guide 39 and the straight shape guide rod 40 in top, guide rod is provided with along the narrow limit R of paper pile S.When more than doing, disposing, (this is illustrated below) was bent away from remaining paper pile with nethermost paper and the narrow limit that makes each separation pig in its back keep being bent away from is in delivery status when separating member 1 was slided below paper pile S, so that transport this paper to processing stand C by sheet-transport belt.
In this example, this sheet-transport belt has the suction nozzle 31 and an endless belt conveyer 35 of two intermittently actives, and each suction nozzle is contained in one can be around 33(Fig. 3 and 7) on the bar 32 of swing, endless belt conveyer 35 rotates to roller 36 operations and has chuck 37(Fig. 1).Move to downwards in the efficient range of belt conveyor 35 on the narrow limit that suction nozzle 31 will be bent away from, and makes chuck 37 can clamp this narrow limit, and paper pulled out under the paper pile S and it is transported to processing stand C.For this reason, suction nozzle 31 its be in a high position and when withstanding on the narrow limit that is bent away from and a suction source (not shown) connect, thereby narrow limit is held, and when making chuck 37 clamp paper arriving its low level with the disconnection of suction source.Also explain detailedly in the back about the action that the paper pile is said good-bye with reference to Fig. 7-7c.
As shown in Figure 4, be contained in the apart distance of each separating member on the chain 18, this distance along narrow limit R size longitudinally, is equipped with separation pig 11 greater than paper pile S between two separating members 1.The quantity of separation pig 11 depends on the size of the maximum paper that needs processing.In principle, need to establish two separation pigs 11 at least for less paper after each separating member 1, the distance between each separation pig and the adjacent separating member 1 should less than narrow edge lengths partly make and only leave separation pig when transmitting paper below narrow limit.
Fig. 8 and 9 is depicted as two transparents view that respectively are shown with a separating member 1 and a separation pig 11, separating member 1 particularly shown in Figure 10-14, has a flange 2 that fixedly has a fixed orifice 2a, in order to be fixed on the chain 18, also has a straight rear portion 7 and at the projection of another side.Have on the top of this projection one straight-though be parallel to the groove 7a at rear portion 7 and therewith groove join in order to put in the face below the narrow limit, this face has three parts, exactly has one and is positioned at the anterior inclined-plane of its fwd 3, one by having the suction face 5 that two facial 5a, 5b inhaling hole 9 constitute by the separating member moving direction.The leading edge 4 of suction face is connected on the planar portions 5a, only establishes one on it in this example and inhales hole 9, and a follow-up again 5b of cambered surface portion which is provided with 8 and inhales hole 9.When separating member slided below a narrow limit, leading edge 4 and planar portions 5a were parallel to narrow limit, and planar portions 5a then abuts on the narrow limit.Suction face is bent away from the plane on narrow limit and its leaning angle with respect to this plane is constantly increased along its trailing edge 8 in the 5b of cambered surface portion.Maximum leaning angle, just the angle between planar portions 5a plane and the trailing edge 8 is in this case between 10 ° and 30 °, be preferably between 15 ° and 25 °, in this example this angle be about 20 ° and when being equivalent to the narrow limit of paper pile and in depositing the storehouse, being pressed against on the separation pig the narrow spring of paper pile from angle.The leading edge 4a of the 5b of cambered surface portion and the face of suction lateral margin 6 are positioned at the same plane that is parallel to narrow limit, and therefore, when separating member slided, this narrow limit was abutted on the arc suction face owing to inhaling, thereby are bent away from remaining paper pile downwards continuously with increasing.
For causing suction effect, inhale hole 9 and when touching the narrow limit of the nethermost paper of paper pile, connect with the suction source at the straight suction face 5a of separating member 1.For this reason, inhale hole 9 by internal channel 10 on the rear portion 7 of separating member, have the hole 9 of leading to the outside '.Along a soup stick (Fig. 7) slippage, in this soup stick, the tubule 42 with the suction pipeline connection leads to a sulculus 43(Fig. 6 in the chain targeting part at this rear portion 7).In this example, these groove 43 topped 3 holes adjacent one another are 9 ', therefore, when separating member process soup stick, under any circumstance have only 3 suction holes 9 to hold narrow limit.According to the length of inhaling face, can be provided with 6-12 and inhale hole 9, wherein under any circumstance only 2-5 is individual has a suction effect.
Observe a separating member 1 and with the separation pig 11 in its back as the direction that moves along chain, plane, lower bevel 15 place is the trailing edge 8 of parallel and a little higher than separating member 1.Therefore, this lower bevel 15 put in the narrow limit that holds for last separating member 1 suction face 5 above, this narrow limit contacts with the bottom locating surface 16 of separation pig immediately, thereby narrow limit is separated with remaining paper pile fully, and the paper pile itself then is bearing in when separation pig is further divided a word with a hyphen at the end of a line on the bearing surface 14 of separation pig.
Fig. 5,7 and 7a be depicted as the guide rod 40 of chain 18, this chain is contained in the next door of depositing storehouse 24 and at a guide groove internal migration, the lower wall of this guide groove is made of a surperficial 40a of guide rod 40 along the narrow limit R of paper pile, its upper wall is made of the auxiliary rod 44 that is fixed on the guide rod.Separating member 1 and separation pig 11 usefulness bolts 46 be fixed on the chain 18 and itself in dividing a word with a hyphen at the end of a line along narrow limit by guide rail 29 guiding, guide rail 29 is fixed on the top of guide rod 40 by intermediate bar 45.Guide rail 29 stretches in the respective upper groove 7a and 17a of separating member and separation pig downwards with its end 29a that dwindles, the vertical side of groove is subjected to the guiding of the inner plane of guide rail 29, and then slide in the inboard of guide rod 40 at the corresponding straight rear portion 7 and 17 of separating member and separation pig.
With respect to the top of chain 18 direction of travel soup stick 41 is inlaid in the bottom of guide rod 40 on narrow limit.This in Fig. 6 as can be seen.The groove 43 of soup stick 41 is communicated with the tubule 42 that passes guide rod, and tubule itself then joins with the suction pipeline (not shown) in suction source.Therefore, at separating member 1 through out-of-date, the suction hole from the suction face 5 planar portions 5a begin always to have 3 inhale holes 9 successively via hole 9 ' and path 10 be communicated with the suction source.
The outside face of guide rail 29 constitutes the antetheca of depositing storehouse 24 simultaneously, enters the paper of depositing the storehouse and bumps on this wall with its leading edge.At this moment, leading edge enter crooked stop spring 30 below, this spring is fixed on the guide rail 29, in order to prevent the paper front edge slippage that makes progress when descending.
The operation of saying good-bye can be summarized as follows with reference to Fig. 7-7c:
Figure 7 shows that separating member 1 is just putting in below the paper pile and the situation of its planar portions 5a when just contacting with nethermost narrow limit R '.Right now, " by the suction nozzle 31 that is in its low level at present it is bent away from downwards, present then just by the chuck that clamping on the belt conveyor 35 37 it is pressed from both sides away; at this moment, 31 of suction nozzles disconnect with the suction source for when having only separation pig 11 to stay below the paper pile, the narrow limit R of front one paper.Fig. 7 a is depicted as narrow limit R ' and just by the suction face 5 of the separating member 1 when the sliding groove 43 through soup stick 41 it is held.Meanwhile, chuck 37 is extracted the paper W that tells previously out below the paper pile, in this example, this paper W slides on the roller 34 that is contained on the axle 33, in further transmitting, lead again, " zero " shape ring 48 is housed shown in Fig. 7 b on this roller by a top roller 47.But save roller 34 and 47 also is feasible.
Fig. 7 b is depicted as the follow-up operational circumstances of saying good-bye, and in this operation, the separation pig 11 of back reaches suction on separating member and above the narrow limit R ' that is bent away from, thereby makes narrow limit R ' further be bent away from remaining paper pile with inclined-plane, its underpart 15.
Fig. 7 c is depicted as positioning states, and under this state, narrow limit R ' is bent away from remaining paper pile fully and abuts on the bottom locating surface 16 of separation pig 11.Under this delivery status, below the paper pile, there has not been separating member 1, the paper pile is bearing on the bearing surface 14 of separation pig 11, has swung to that it is high-order and just can hold narrow limit R ' with suction nozzle 31 that the suction source is connected this moment.Under this delivery status, paper is flat.Further operation be make narrow limit R ' with suction nozzle to lower swing, this and above-mentioned narrow limit R " situation identical.The chuck 37 of belt conveyor 35 is clamped paper W shown in Figure 17 and the 17a and its inner space via endless chain 18 is transported.
Shown in Fig. 7 c under the delivery status, chain 18 stops temporarily, for example persists for tens seconds, so that suction nozzle 31 can hold nethermost paper reliably above-mentioned.Thereby can have two separation pigs 11 and two suction nozzles 31 to be positioned on the same horizontal surface when chain stops is pressed against narrow limit on the locating surface of separation pig under suction nozzle is in high-end trim.But also can not adopt this state of chain, and make two suction nozzles when holding narrow limit between two separation pigs.
After measured, the number of paper that adopts described sheet feeder per hour to tell can be up to 4000, and this has just satisfied the requirement of modern numbering machine and guillotine work speed, deposit paper pile number in the storehouse and often should remain on 4-40 and open in this scope roughly.
Between separation pig 11 and the separating member 1 and separation pig distance each other preferably be not more than the length of the suction face 5 of a separating member, particularly be not more than this length half, make the whole length that is bent away from narrow limit be in delivery status well.In this example, this distance be a bit larger tham inhale three of face length degree/once or approximate 1/3rd of a separating member or a separation pig length.
Can make the narrow limit of the paper that holds not only around 6 bendings of the face of suction lateral margin by the customized design of the separating member arc being inhaled face 5, go back the straight line distortion that is parallel to this lateral margin 6 that winding is thought simultaneously.Because paper, particularly the screen resilience of currency paper under torsional deflection is generally greater than the screen resilience under the simple bending distortion, the narrow limit that is just being picked up may take up down the narrow limit of a piece of paper, it is abutted on the narrow limit that is picked up slightly, under the situation of torsional deflection, the narrow limit of following a piece of paper is certain to come back to its original state before the narrow limit that need are told reaches its maximum torsional deflection.This torsional deflection is made just because of the elasticity of its instinct is just unlikely in may be taken up the down narrow limit of a piece of paper thereupon.The process of this hypervelocity can be confirmed by stroboscope.
Under the situation that adopts above-mentioned sheet feeder, separating member 1 is inhaled the planar portions 5a of face and the bearing surface 14 of separation pig 11 tilts about 20 ° with respect to depositing 24 bottoms 26, storehouse, thereby make narrow limit R in depositing storehouse 24, take a corresponding heeling condition, and after telling, being in horizontal transmission state accurately, the paper of just telling is plane.
But, in another embodiment shown in Figure 19-19c, also can make the planar portions 5a of separating member 1 ' suction face and separation pig 11 ' bearing surface 14 with deposit bottom of the reservior portion 26 and be in the same plane, make all paper in depositing the storehouse, do straight piling up.Saying good-bye when operation, make nethermost narrow limit R ', just situation is identical as previously discussed, inhales the face radian by separating member 1 and is bent away from horizontality, thereby make it downward-sloping and be in delivery status (Figure 19 c) with respect to residue paper pile.Figure 19-19c is equivalent to each state of Fig. 7-7c, is therefore no longer illustrated.Wherein identical parts have adopted identical label.
Different with sheet feeder shown in Fig. 1-18, in Figure 19-19c illustrated embodiment, the paper W that tells be as shown in figure 19 directly by belt conveyor 35 ' chuck 37 ' gripping, saved suction nozzle, this belt conveyor two separation pigs 11 ' between the space in contour with it operation, thereby make the narrow limit R ' that is supported on separation pig 11 locating surfaces can be under delivery status by chuck 37 ' it is clamped.As shown in figure 19, the paper W that separates is by chuck 37 ' pull out under the paper pile it a bit of.In addition, sheet feeder shown in Figure 19-19c has different chain guide frames, paper pile leading edge lean the antetheca 29 of depositing the storehouse ' on, the slightly different separating member 1 of structure ' and separation pig 11 ' be is by the direct guiding of the soup stick 41 with guide rail effect.
The present invention is not subjected to the restriction of above-mentioned each example and can making multiple scheme on the block construction and on arranging and on the quantity at used separation pig
